Merge tag 'microblaze-v7.4' of git://git.monstr.eu/linux-2.6-microblaze

Pull arch/microblaze updates from Michal Simek:
 "Some issues were found by AI but nothing dramatic.

  The signal changes are related to upgrading the toolchains supported
  by AMD. Hardened MicroBlaze cores are used in AMD/Xilinx chips, and
  they will be supported for another 10+ years. New tests were run as
  part of this effort, and that's how the signal stack issues were
  found.

  The KUnit patches have been reviewed by David, and he agreed that they
  can go through my tree.

  Summary:
   - Add Kunit support
   - Update signal handling

  Small changes:
   - coding style, typos
   - don't use "new" ASM pseudocode
   - fix refcount leak in cpuinfo code
   - prevent ptrace writes to MSR and pt_mode
   - enable Xilinx DMA driver by default
   - build userprogs for the correct endianness"
